To all whom it may concern:

Be it known that I, DANIEL i'fiess'rnn; a citizen of the United States, residing at Abbott, in the county of Hill and State of Texas have invented certain new and useful Improvements in Motor Plows, of which the following is a'specification.

. This invention relates to motor plows,

andhas for its object the production of a simple'and efi'icient means for facilitating tlIGIZIISHIg or lower ng of the several plows supported upon the plow frame.

. Another object of this invention is the a through the rear portion] of theplow with the forward portionthereofbeingshown in side elevation, V a Figure3 is a longitudinal section through a portion ofthe plow. frame-showing the means for changing the pitch of the harrow blades or cultivator blades carried by the cultivator supporting arms or beams.

By referring to the drawings by numerals it will be seen that 1 designates the frame of the plow which is-supported upon a plurality of forward wheels 12, and a plurality of rear driving-wheels The body or frame of the plow may be formed of the usual tractor type and may be formed of any suitable or desired construction for obtaining the desired results. The -wheels 3 are driven by means of a plurality ofsproclret chains 4: which chains are operated by means of a driving shaft 5 as shown in Figure A suitable steering wheel 6 is carried upon the frame 1. and islocated directly in front of the operator seat 7-. The operator seat 7 is preferably mounted upon a fuel supply tank 8 as shown in Figure 2 of the drawings.

' The frame 1 is providedwith a trans versely extending brace 9, and this brace 9 constitutes a support orguide for the plow supporting standard .10, This plow sup- Application filed January 2c, 1918. sem No. 213,900,

porting standard provided with a blfurcated upper end 11 which bifurcated upper end 11 fits aroundthe brace 9 thereby facilitating the guiding of the plow supporting standard 10 thesanie israised and lowered. A stop pin 12 is carriedbetween. the blfurcated outer end of the standard 10 forylimiting the downward movement of the standard 10 upon the base -1. A suitable plow blade 13 of the'desired construction is porting "standard 10.

carried bv the lower end of the plow sup A pair of side beamsor cultivator blade" support ng arms 1 1' are secured at, their forward ends to the hinges 15,. which hinges are carried by the depending arms 16 car ried by the brace 9'. A cultivator blade 17 is supported upon each arm 1d near the rearthereof and, upon opposite sidesand these blades 17 are hung upon supporting arms 18, the arms 18 being carried by the pivoted bolt19 These blocks 19 are provided-with reduced ends 20,'the reduced ends 20,being 'journaled within the arms 14 for thepurpose of permitting the reduced endsQO to. rotate within the apertures 21, -in this way permittingt'he angle of the cultivator blades 17 to -b e changed.

Am -operating lever 22 is carried'upon-each side of each of the arms li and engages a plate 23 for the purpose'of permitting the 'lever 22 to be held in a set position. The" lower end of each lever 22. is connected to links 21 as shownin, detail in "Figure 7, the links 24 being connected to the cultivator supporting arm 18. 'It should "be understood thata lever 22 is providcdfor the operation of the respective cultiva'tor'blades supported upon the opposite sides of the arms 14.

From the foregoing description it will be seen that the cultivator blades f1? may j be tilled to a nesircd angle by the cpera tion of the lever and it should be understood that these blades mav be'indi'vidu-allv operateddue to the fact that eachblade I I operated by a separate operating lever 22 as shown in Figure c '7 i A. pluralityofguidmg plates 24? are seplates 24* are provided with depending parallel arms 26, which are arrangedin spaced-relation for the purpo'se'o'f constituting'a guide for the cultivator blade supcured to the transversely extending rear guards 25 of the frame Land these guiding porting arms 14, these arms being adapted V i to extend between the parallel depending arms or fingers 26 of the guiding plates 24. This structure is clearly shown in Figure 9 of the drawings.

A lever supporting standard 27 is supported upon the rear transversely extending bar of the frame l and this standard 27 carries a lifting lever 28 and an operating lever 29, the operating lever 29 being connected to a link 30. the link 30 being in turn connected to the plow supporting standard 10. Each of the cultivator supporting arms 14 carries a yoke member and each yoke member 31 is connected to coil springs 32, the coil springs 32 being in turn connected to the links the links in turn being connected to the lower end of the lever 28 as shown in Figure 3 of the drawings. It should be understood that when it is so desired the standard 10 may be raised and lowered by swinging the lever 29, the lever 29 being raised in a convenient position for operation of the driver of the machine who is mounted upon the seat 7. When it is desired to raisethe cultivator supporting arms 14, the lever 28 may be swun upon the quadrant 35 thereby yieldably raising the arms 14 and throwing the cultivator blade 17 out of engagement with the ground.

A lever 34 is also pivotally mounted upon the standard 7 and this lever 34 engages the link 40 having a hooked lower end 35, the hooked lower end 35 engaging the planter supporting arm 87, which is pivotally supported as indicated at 36. A planter shoe 38 is carried by the planter supporting arm 37 and is adapted to deposit seed in the furrow which has been formed by the plow 13. By considering Figure 3, it will be seen that the planter 38 is raised and lowered to an inoperative position when it is so desired by swinging the lever 34. The planter 38 is provided with a planter discharge spout 39 as shown in Figure 3. Suitable covering plates 43 are extended upon the cultivator supporting arms 14 and are adapted to extend upon opposite sides of the planter spouts 89. These covering plates 43 are supported upon suitable supportin arms 44 carried by the arms 14 as shown in Figure 5 of the drawings. A. suitable fertilizer supporting con tainer 41 is supported in the rear of the frame 1, and is provided with a discharge spout 42 extending in the rear of the planter The wheels 3 may be adjusted to a suitable position for raising the cultivating, plowing and planting means out of engagement withthe ground over which the motor plow is passing. It should be further understood that in view of the fact that each of the wheels 3 upon the opposite sides of the frame 1 is individually adjustable. the frame may be adjusted to travel conveniently upon an inclined surfaceysuoh as side of a hill, for instance while planting a field located upon the side of the hill or plowing the same.

A digging plow 51 is supported upon one side of the frame 1, and this digging plow is supported by the vertically extendiin, standard 52 the standard '52 being in turn connected to an adjusting lever 53 pivotally mounted upon a standard 54. It, of course, should be ruiderstood that any suitable number of plows or cultivating devices may be supported upon the frame merely by multiplying the parts disclosed as this would not involve invention. and it is not desired to limit the invention to any particular number of cultivating, planting or plowing devices which are supported upon the frame.

It should be'understood that the cultivator, planter and plowing devices may be easily removed from the frame 1 when it is so desired for the purpose of allowing the device to be used as a tractor or an automobile without using the respective implements supported upon the frame. However, when it is desired, the device may be applied to the frame and may be thrown into and out of action by means of the operating levers clearly described above.

It should be of course understood thatcertain obvious mechanical changes may be made in the present device without departing from the spirit of the invention, so long as these changes fall within the scope of the appended claim.

What is claimed is:

In a plow of the class described, a frame having a cross bar provided with fiat parallel front and rear sides, .a plow standard having its upper end bifurcated to pro vide parallel arms, said cross bar closely fitting said bifurcated standard whereby the standard is guided vertically by said cross bar, an adjusting lever pivoted to the frame and spaced longitudinally of said frame from the standard and a link having its lower end connected to the standard below the cross bar and its upper end connected to the lever, said link being angularly dis posed with relation to the standard whereby to constitute means for adjusting the height of the standard and for bracing the latter against backward movement at its lower en In testimony whereof I a flix my signature in presence of two witnesses.

DANIEL WEBSTER.
